How to use brick mold？

1. Use the 90# gear box oil or mix with used food oil to paint inner the moulds, then use the brush to coat the moulds in order to release the concrete blocks easily.

2. Silver sand: 13mm stone (gravel) cement(400#)=3:2:1, pour the mixed concrete into the interlock moulds, start the vibration table at the same time and keep vibrating until the concrete in the moulds is level and some bubble come out, then send to warehouse (with good ventilation) for 24-36 hours drying.

3. Release the fixed screw and loose the moulds, then move the block out.
